I dont know if i really had sexual intercourse and i used an after pill. i got my period after that incident, but not the month after. pregnant?

Small chance pregnan: It sounds like you possibly had intercourse, used a morning after pill, had a period, but no period since. Women after have an irregular period after the morning after pill, so that might have made the next period not come at the usual time. Pregnancy is possible, since sometimes the morning after pill doesn't work. You might want to check a pregnancy test and make sure it is negative.
